it sounds very odd but I play this as GSF, sounds like 2 voids.

I play this is choice of slams with exactly 5 spades.
and the result can be plotted on a graph.

It just offers a choice of small slams, but he might become interested in a grand slam if opener shows something interesting.

If opener has something like AQx AJx KQJ10x Kx, a grand slam almost certainly just depends on having enough key cards. If opener has AQx AJx KQ10xx Ax, responder's diamond holding will be critical. And we have three whole bids available for exploration. 2NT auctions are great, aren't they?
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

5NT = pick a slam (6NT or 6♠), I have a 5 card ♠.

It doesn't show willingness to play grand, you have methods enough to investigate.

What do you play:

2N-3♥
3♠-4N

as ?

I know I play it quantitative with some 5(332).

Since 2N-5N says bid 6 or 7 quantitative, I see no reason why the same logic should not apply, we have 36-38 between us and I have a 5 card spade suit partner.

If you have very sophisticated methods, you might choose to take it slowly instead, but certainly in a pickup partnership without agreement I'd expect it to be this.

4NT = quant, 5NT = choice of slams.

This is far more important than any kind of grand slam try, so unless you can do both you need the choice of slams imo.

I think most pairs should know whether opener has fit or not, so 5NT is 'We're gonna play 6 at least but if you have you maximum let's play 7'. If 3♠ doesn't show/deny fit then I don't know, might be choice of slam.

sorry guys, but I play 3♥->3♠ = 3+ spades, 3NT = 2 spades.

I don't play Pick a slam on any situation, but if playing it I still see no point once the spade fit is unveiled.

Then 5NT should just be invitational to 7NT like 2NT p 5NT. I still see no reason for you to play the GSF there (in fact I see even less reason if 3♠ denies a fit). Transfer at the 4 level then bid 5NT if you want it.

5332, partner is welcome to bid any suit, not just 6S or 6N, as we might belong in a 5-3 fit. I will pull with a doubleton.

To bid GSF bid texas then 5N

Most likely.

"Pick-a-slam bids" are one of those notions that don't appear in most the bidding textbooks, and don't exist in practice outside of adv+ level regular partnerships. It would be a very fruitful area, if someone were to write up some guidelines sometime.

Even then, in this particular auction 5NT is so high that it's going to need to carry an extremely specific meaning, and it's hard for me to imagine very many of those other than the ancient standard one that are appropriate.

It's really a very understandable error to think this 5NT bid invites a grand. After all:

1NT - 4NT = inviting slam
1NT - transfer - acceptance - 4NT = inviting slam
1NT - 5NT = inviting grand
1NT - transfer - acceptance - 5NT = ....

Obviously someone who hasn't come across it before or who tries to extrapolate from similar bids might think the last auction invites a grand.
